I loved those tiny 20-30 part Space builds from the ’80s myself, and that’s what got me into this as a kid. Now, I build much bigger, but still love all genres of tiny tablescrap MOCs as support for the bigger stuff.
As for storage space, my LEGO part collection and my MOCs have destroyed all the boxed sets I used to have, and now it’s all in boxed up display MOCs from past events we’ve done.
Moving boxes and parts around, I just rediscovered the Georges’ Space house from the S.W. Randall I display we collaborated on years ago, for example, and the Spacer family and vehicles I built. It has come apart in storage, but it’s still fun to remember, and its construction gives me new ideas!
So, welcome! Start a thread for your own building experiences, maybe a journal here. Feel free to start a thread about any LEGO question you may have, or just tag others who might be into the same things you are. Cruise the Recently Active topics often, and reach out to connect and build. Just like LEGO parts, builders of different kinds can connect in new and unique ways.
